IMPROVEMENT IN CAPS FOR OIL-(JANS.

Be it known that I, JOSIAII I-I. News, of Centre Abington, in the countyof Plymouth, and State of Massachusetts, have invented a new and usefulImprovement in Caps for Oil-Cans and other vessels; and I do herebydeclare that the following is o full, clenr, and exact descriptionthereof, which will enable others skilled in the art to make and use thesame, reference being had to the accompanying drawing, in which- Figurel represents aside elevation of an ordinary can, with my improvementapplied.

Figure 2, a. sectional elevationthrough the line :i: su, fig. 4. I

Figure 3, a plan or top view when closed.

Figure 4, a similar view when open.

Similar letters of reference indicate like parts.

The object of this invention is to provide a convenient device foropening and closing the necks or mouths of oil-cans und other vessels.

Myinvention consists in the combination of a revolving cap or cover withthe neck andl mouth of the can or vessel, the construction of myimprovement being such that, when the cap is revolved in one direction,the

can or vessel will be opened, and when the cup is turned in the contrarydirection, the can or vessel will be closed.

A, in the drawings, represents a. can of' theordinary construction.-'lhe neck B is covered on its top byu. diaphragm, a, in which is cut anopening, f, through which to ll in the liquid.` y

On the sides of the neck a screw-thread is formed, upon which fits thecap, C, which has also a thread formed on its interior sides,corresponding with those of the neck of the can.

`The cap, C, has also on its upper surface an opening, c, nearlycorresponding with the openingf ot' the can.

Within the upper part ofthe cap, C, is placed n cork, rubber, or otherpacking, E, which is firmly secured in the cap, C, and said packing hasan opening, correspondingr to vthe. openings c f.

The bottom part or flange D of the cap, C, is slotted or partly cut awayat cl, to allow a small pin, g,

,attached to the can A, at 'or near its neck, to play therein, und which`has n twofold purpose: first, to prevent the cap from .being turned toofar either wny, in opening and closing the can; second, to p fromfalling oil` while opening the can for filling in the liquids. l i

' In opening' the can or vessel for filling in thc liquids or-otlrercontents, it is necessary to turn the top, C, in the direction indicatedby the arrow, 3,) by which movement the opening, c, of the cap will comeinto line with that of the opening, f, of the diaphragm a, as shown infig. 4. To close the can, the movement of the cap is simplyreversed,.the screw-threads' servingdo depress thc cap, and compress thepacking upon the opening, f, and thus seal the some7 so that allleakageof gas'or contents is avoided.

Having thus described my invention, I claim as new, and desire to secureby Iretters Patentv 1'. The construction of the revolving perforatedcap,V in combination with the neck of the con or other vessel,substantially as herein shown and described. i

revcnt the cap, C,

2. Iialso claim the combination of the senling-packingE with the cup andthe diaphragm a, substantially n as herein shown and described.

3. I also claim the slotted flange l), in combination with the stop-ping, as and for the purpose set forth.
